Heat transfer along a chain of nanoparticles — •Christoph Kathmann1, Philippe Ben-Abdallah2, and Svend-Age Biehs1 — 1Institut für Physik, Oldenburg University, Germany — 2CNRS, Laboratoire Charles Fabry, Palaiseau, France
In the near field, the radiative heat flux transferred between two bodies can overcome the predictions made by Planck's law by several orders of magnitude due to the contribution of evanescent modes. We consider a chain of SiC nanoparticles with the distance between the particles being small enough to allow the coupled surface phonon polaritons to propagate along the chain. The resulting heat transfer is calculated numerically exact using fluctuating electrodynamics and compared to results from a ballistic and a diffusive approach based on Landauer and Boltzmann equation.
